Something simple that fixed this issue, Uninstall all .net cores. and launchbox Download net core 3.1. In your downloads folder be sure to install the core as administrator, pay attention to which folder it installs usually Program Files x86, when you re install as administrator Launchbox be sure to change the install folder to the same folder as dotnet again in windows 11 this is Program files x86. I think the issue is the installer puts it in your users folder for windows and the .net runtime, framework, and core are installed in the C:/ drive. Its like the program looks for the dotnet within the same subfolder installed. Hope this helps
